Abstract: Objective To evaluate the guiding role of capsule endoscopy (CE) in choosing the access route of double-balloon enteroscopy (DBE) for small bowel diseases. Methods Patients with complete CE and with small bowel diseases confirmed by DBE were enrolled. The lesion location found on CE was represented by the time index, which was the ratio of access time from pylorus to lesion over access time from pylorus to ileocecal valve. Based on our previous retrospective evaluation, oral approach was selected when the index was ≤0. 6, otherwise the anal access would be chosen. Accuracy of time index predicting DBE access rout was evaluated. Results Data of 60 patients undergoing both CE and DBE were evaluated. All lesions detected by CE were confirmed by DBE, with 41 via oral route and 19 via anus. Based on the time index with threshold of 0.6, the accuracy of selecting the insertion route of DBE was 100%. Conclusion DBE is an effective approach to confirm CE results. In patients with complete small bowel investigation by CE, the insertion route for DBE can be reliably indicated with time index based on the CE results.
